Linking between entities in different datasets is a crucial element
of the Semantic Web architecture, since those links allow us to
integrate datasets without having to agree on a uniform vocabulary.
However, it is widely acknowledged that the owl:sameAs construct
is too blunt a tool for this purpose. It entails full equality between
two resources independent of context. But whether or not two
resources should be considered equal depends not only on their
intrinsic properties, but also on the purpose or task for which the
resources are used. We present a system for constructing contextspecific
equality links. In a first step, our system generates a set of
probable links between two given datasets. These potential links
are decorated with rich metadata describing how, why, when and
by whom they were generated. In a second step, a user then selects
the links which are suited for the current task and context, constructing
a context-specific “Lenticular Lens”. Such lenses can be
combined using operators such as union, intersection, difference
and composition. We illustrate and validate our approach with
